To all whom it may concern:

Be it known that I, Srnrnnn Nnwcoiunn \VELLiNcroN, a subject of the Kingof Great Britain and Ireland. residing at 3!) Mincing Lane, London, E.(,1, England, have invented. certain new nd useful Improvements Relatingto Apparatus for Discharging and Quenchin Coke, of which the followingis a. specification.

This invention relates to apparatus for discharging and quenching highor low temperturc coke or the like from vertical retor s, and is moreespecially applicable for the discharge of the residue of distillationat comparatively low temperatures. The invention has for its object toeffect the discharge of the coke from vertical retorts so as to avoidwaste, to improve the coke, and also to effect the quenching of the cokein a simple and effective manner without con tai't of the coke with thewater used. and generally to provide an apparatus simple in constructionand cfl'cctive in operation.

According to the invention I provide receptacles for the reception ofthe whole charge from the retorts, and I mount the receptacles upon acarriage torun on rails mounted immediately beneath the retort set ting,so that thus -the receptacles mounted upon the carriage can he broughtbeneath the respective retorts of the battery or setting in succession.I provide gear for the purpose of lowering the charge into thereceptacles, the gear being niounted advantageously upon a separatecarriage and mounted to run beneath the carriage upon which thereceptacles are mounted. According to the invention also the gearcomprises one Or more ram adapted from beneath to pass through thereceptacle 51* receptacles to take the weight of the bottom 'cover plateor door and to lower the bottom cover plate or door withthe charge intothe receptacle; the gear advantageously comprises an electro-motor andcontroller with a clutch conveniently provided. by which the motor maybe employed for driving the carriage upon which the gear is mounted torun on rails. or in the alternative for lifting or lowering the rams,while the gear also comprises means manually operated by .wluoh fi e adu men of the p ion i oi -side and beneath ram'or rams and carriage mayhe climbed, or if necessary also of the carriage upon which thereceptacles are mounted.

The invention comprises the constructional features which arehereinafter described in an apparatus provided according to theinvention. 4

1n the accompanying drawings is illustrated, by way of example, anapparatus according to the invention.

Figure 1 is a side elevation partly in section of a modifiedconstruction of the apparatus.

Fig. 4 is a sectional elevation of thr ge'iring corresponding to Fig. 3taken on lin: of spindle j.

Fig. 5 is a front elevation of the illustrated in Figs. 3 and 4.

In carrying the invention into effect as illustrated in Figs. 1 and 2 inthe construction of u quenching machine provided ac cording to theinvention. I provide two receptacles d mounted upon a carriage frame 8in SllGlLPOSlliOIi that two alternate vertical retorts of a battery maybe discharged multaneously and I provide each receptacle. with a slidingcover plate 1 provided on each the plate with toothed racks adapted tomesh with pinions 2 mounted each upon a spindle 3 carried immediatelybeneath or at the side of the outwardly flaring upper end of eachreceptacle. A chain wheel and chain 4 (Fig. 2) serve to cause therotation of the spindle 3 and to cause the cover plate 1 to slide to orfro for closing or opening the top of each rece tacle. Upon the carriageframe 6 a tan 5 is mounted adapted to contain the water 'forquenchingthe coke in the respective recep- The lower ends of thereceptacles tacles. pass 'into the tank so that at their lower ends thereceptacles are completely surrounded hy the water contained inthe tzmk.Holes 6 are formed in the top of the tank 5 in a, position correspondingto the respec: tive receptacles and of a larger diameter than that ofthe receptacles so that thus 0:! the ater be ng pray fr m he upper endof the receptacles on to the outer surface thereof the water returns tothe tank.

I mount a pump and motor equipment, n a position above the tank asillustrated in Figs. 1 and :2 with the suction pipe 7 ex tending to nearthe bottom of the tank and with its upper end connected to the pinup Swhich is operated hythe motor 9. 121m pump outlet discharges into thewater pipe 9 by which water is supplied to the spray pipes 10 whichcompletely surround the re spective, receptacles, the spray pi ms 10heing provided with orifices throng iout their length by which water isdirected inwardly toward the outer surface of the receptacle. A platform11 serves for access by the attendant to the up ier part of thereceptacles.

A central overl low outlet pipe 9 may he, provided in the tank in theposition indicated in Fig. 1 and partitions 12' may extend into the tankshort of the hottom as a means for preventing the water being spilled ona too sudden movement of the quenching machine or on a too suddenai'i'estiiient of this movement. I

The motor equipment and gear for causing the movement of the ipienchingrmachine upon the rails upon whici. it. is mounted is advantageouslyprovided in the front part of the carriage frame as illustrated in Fig.1, the motor hcing indicated by 1?). the ontroller by 13'. and the gearhe H hy means of which movement is imparted to the axle 15. A contactarm 16 is provided in position beneath the carriage frame r hy means ofwhich current may he passed to the. motor from conductors t? of a threephase circuit mounted near the side wall of the well in which thedischarging machine is mounted as illustrated in 'l ig. 2.

Each of the receptacles at its hasc and on each side is provided with asliding plate 18 and these sliding plates are provided with toothedracks engaging with segments 19, One. of the segments is mounted upon aspindle 2U transversely disposed arrow the carriage frame while anoperating itiver 21 is mounted upon the outwardly protruding extremityof the spindle 2t) and this operating lever 21 is extended at one sidefor the iurposo of connection with the cori'cspoiidmg toothed segment 19hy means of a link 22, while at The other side of the spindle 20opposite to thatv upon which the operating lever 21 is mounted a shortdownwardly e'iz tending tlllll is provided corresponding to thedownwardly extending part of the lever 21 for eonnection'with a secondlink 22 mount,- ed upon the other side of the carriage frame. A link 23is provided on each side to connect. the respective sets of segmentstogether of each of the receptacles so that the respective slidinglatest 18 of each receptacle may be operat by the single operating handlever 21. The, normal position of the sliding plates 18 is indicated inFig. l and these, protrude within the receptacle and form ledges on eachside for carrying the hot tom door .24 upon which the charge issupported.

The inwardly protruding edges of the sliding plates 18 are formed withcurved downwardly Having flanges :25 which serve to lll'lllg the rain12h on its upward movement into precise coincidence with the. center ofthe receptacle.

It will thus he understood that the hottom doors of the rctoi'ts to hedischarged are retained with the charge in the receptacles. For thispurpose the carriage lil'illlit' is extended at one end in order thattwo spare doors it may he transversely mounted in position thereoncoiicsl'ionding to the posi tion of the retorts and these alter the discharge of the rctoi'ts may immediately he lifted into position to ('lOscthem so that they may he immediately i'c-charged.

(tripping arms :27 may he mounted hencath the carriage t'i'anie w toprevent liahility ot the carriage frame hein g upset on the sparehottoni doors 2'! heing lifted off the ironic. These gripping arms 27engage the slides of the respectiie rails upon which the carriage frame1* i mounted to run in such manner that they do not normally contactwith the rails hut permit oi freedom of movon'icnt.

in carrying the invention into etlcct in the construction of thedischarging: machine as illustrated, l proiidc a liasc'platc 23% uponthe carriage l'ranic f il'o hosscs it! suitably provided for thereception f hall hcarings up n which worm wheels may rotate the normwheels lining prmidcd with an in ternal thread ciirii-spondine to theexternal thread provided upon the rain spindles 1 i provide alongitudinal shall I: with worms in dctcl'inincd position for engagementwith the worm wheels rclcrred to, so that thus the thr aded spindles 5/of the rains may he moved upwardly or downwardly on the rotation of thclongitudinal shall it in one direction or the other. "lhe worm wheel mayhe suitahly incascd. as may also the worm. For the purpose of preventingthe rotation of the respective threaded rain spindles r/ l mount on eachof their lower extremities an arm 3U which is provided with lateral lugs31 at the end to engage the i'cspcctiic lateral edges of thecorresponding arm near its boss 32 by which it is mounted at the end fthe threaded spindle. Any other means for the same purposiu may however,he [)lUVltlttl.

The motor 33 is ad 'antageously mounted in direct line with thelongitudinal shaft 7:. and one end of the motor spindle j dis posedclose to the end of the longitudinal shaft h, and the respective members34, 35 of a clutch are mount ed on the adjacent ends of the motorspindle and longitudinal shaft, so that thus the longitudinal shaft inmay e caused to rotate witlr'the motor spindle j or be disconnectedtherefrom according to the position of the movable member 35 of theclutch.

Upon the end of the longitudinal shaft h adjacent; or upon the boss ofthe clutch member 34 carried thereby, a toothed pinion 36 is mounted toengage with :1 corresponding toothed wheel not shown mounted upon aspindle 38 through which movement is imparted to a circuit breaker 39disposed in an adjacent position so that on the rotation of thelongitudinal shaft h on the operation of the motor 33 in one directionor the other, that is to say, in the direction necessary for the upwardor downward movement of the ram 26.excessive movenu-nt of the ram may beprevented. The sign 40 indicates a brake of any usual construction,preferably a mag nctic brake, whereby movement. of the spindle of themotor may be checked or stopped. A magnetic brake 40 may also heprovided to arrest the movement of the motor 33 and motor spindle.

Adjacent the clutch 34, 35 and immediately beneath the extremity of themotor spindle j gear is prmided by which movement may be imparted to asecond longitudinal shaft I through which the rail wheels are rotatedfor the movement of the carriage frame f from place to place. This gearmay consist of two toothed wheels 41, 4:]. the larger 41 of which may bedisposed so as to he engaged by the toothed pinion 35 integrally rovidedon the movable member 35 of the c utch, while the second toothed wheel42 may be integrally provided with the toothed wheel 1 1,and this secondtoothed wheel 42 may engage with a toothed wheel 43 mounted at theextremity of the second longitudinal shaft 1. The second longitudinalshaft l is advantageously mounted beneath the carriage frame 7 and isadapted to cause the movement of one of the axles 44 by which thecarriage frame f is supported. For this purpose a wormniay be mountedupon the extremity of the second longitudinal shaft Z to engage with thecorresponding worm wheel mounted upon the axle 44. t

The respectiye adjacent ends of the shaft h and spindle j are carriedwithin suitable' hearings upon a support 53 over which a cover 54 isapplied and bolted.

I provide the hand lever 46 for operating the clutch 34,. 35 upon aspindle 48 disposed -m a convenient position accessible to the attendantwho may stand upon a platform 49. disposed lower than the level of thetop of the carriage iramef a: corresponding hole tht mechanism isrendered operable by the hand wheel 52. For this purpose a gear wheel 55is mounted upon the end of the motor spindle j in a position adjacent tothe clutch 34, 35 before referred to, and this gear wheel 55 engageswith a corresponding pinion mounted upon a spindle 57 disposed parallelwith the motor spindle j. The spindle 57 is at one end carried upon thesupport 53 and at the other upon the supporting frame 58. This latterserves also to support the motor spindle and to receive one side of thecasing or guard 59, which at the other sidcis mounted upon the support53. At the end of the spindle 57 the hand wheel 52 is mounted in aposition accessible to the attendant so that on the clutch 51 intendedfor permitting operation by hand being caused to engage, the brakemagnet is lifted to permit of easy operation of the gear by hand. Bysuch means it will be understood that the hand operated mechanism isavilable for adjusting the position of the carriage frame f in relationto the receptacles d mounted on the quenching machine as well as theposition of the rams 26.

A contactlcvcr 60 may be provided to extend above the level of thecarriage frame and-pivotally mounted in position thereon in such mannerthat it may be -displaced on the contact lever 16 of the quenchingmachine being moved in position over it. For this purpose an arm on thecontact lever extends below its pivoting point and is engaged on eachside by means of spiral springs which tend to maintain it in its uprightcentral position. The contact arm 60 is advantageously provided-withthree contacts where, as is preferred, a three phase electric circuit isused.

It will be understood that the quenching machine is adapted'to run uponrails over a pit within which the discharging mechanism is adapted torun upon rails of a narrower gage than that upon .which the quenchingmachine runs, the pit being provided centrally sufficiently deeptopermit of the complete retraction of the ram spindles. Such anarrangement of the quenching and discharging machines is indicated inFigs. 1 and 2. i

The operation may be readily understood III from the foregoing. I bringone of the carriage frames, preferably frame e, into position over thepit, either before or after I have cooled or quenched the coke in thereceptacles. I then bring the lower frame f into position and cause therams to rise and thus push the coke out at. the top.

The receptacles may he discharged in any conrenien' manner. I prefer todischarge them by lifting the coke after it has been cooled so that itmay he deflected on to a. conveycr and then passed away for loading intotrucks or harges. the coke being thus hroken into large pieces andwithout C6D siderahle waste.

It will thus he seen that on the two carriage frames movahle aithrespect to each other. I have embodied all the parts necessary foreti'ccting rapid and safe discharge of coke. The lower t'ramc may servethe upper frame 0 or several of them, in any posilionand at any timedesired. ()nc upper frame may serve several ovens.

1t will he noted that in the operation of my device. the machine as awhole ishrought. to approximate position with respect to the ovens bymeans of motor 2%, "1y means of motor 13, the carriage t'rame c isbrought to position withrespe t to alternate retorts of a coke ovenbattery. These retorts are dis-- charged into receptacles n which areclosed. The. hot coke is cooled therein hy spray pipes, 10. Aftercooling it. is discharged preferably at the upper end upon a con veyer.ltleantilme the machine may have heen permitted Ito receive and coolcoke from other retorts ot' the hattery.
